Synthesis and luminescence properties of a series of tris(4-styrylphenyl)phosphorus-(iii) and -(v) compounds and of a [Cu(PR3)4]BF4 complex

Abstract

The series of compounds PR₃, OPR₃, MeR₃PI, Cl₂PR₃ and [Cu(PR₃)₄]BF₄ (R = (E)-4-(4-tert-butylstyryl)phenyl) has been prepared and optical properties explored by absorption and fluorescence spectroscopy. The effect of geometry and coordination number on luminescence intensity is presented.
